*Minh-* IMPROVEMENT IN GRAIN-DRILLS.

www

The Schedule referred to in these Letters Patent and making part of the same.

To- 'gqhom it may concern.'

Be it known that I, W. N. HAMILTON, of Odessa have invented cert-aiu new and useful Improvements in Grain-Drills; and I hereby declare the following to he a full, clear, and exact description ofthe same, reference being had to tlie accompanying drawings, in which-f Figure 1 is a. perspective view ci' a port-ion of' the hopper of a grain-drill, made in accordance with my invention. Figure 2 represents a longitudinal vertical section of the same.

Figure 3 represents a transverse vertical section, on the line a; x, tig. 2. v Figure 1 represents a like section on the line y y,

.Heretofbre it has been usual to malte the bottoms of the bowler-boxes oi seed-drills of wood, in which are cut thc tapering holes, i'or the discharge of the grain to the sponts.

'Ih employment ol" such botton'is is expensive, owing to the hand-labor required in order to properly make and rit them; and, moreover, as the i are usually made tlat or horizontal, the dust, straw, and other refuse, mingled with the grain, arc not discharged as they should be, but accumulate in frequently cleaned in working order.

lo remedy' this difficulty, I make the bottom of cast-ir0n, so moulded as to have gradually-inchned sides around the discharge-opening, thus obviating the box, which, out, in order to keep the machine the dieulty heretofore experienced with regard to the accumulation of dust, Sac., for, as the bottom presents inclined surfaces to the grain, the dust and refuse will not accumulate, but will graduallywork their Way over the inclined bottom, and, along with the seed, through the dischargeopening to which the inclined surfaces of the bottom lead. And again, in forming and shaping the bottom, no labor is necessary, as they are cast in-the precise shape required, and nothingremains but to grind or polish them oi, it this be found necessary, and to apply them to their boxes. But little metal is required, moreover, to produce them, for they may be made quite thin, and therefore with great economy.

My invention consists in casting, with the bottoni, a cut-oft' stud or projection, at each of the discharge-apertures in the bottom. 'Ifhis cut-cti" serves, in connection with the :uljusting-slide 'usually employed in drills, to regulate thc amountot' grain which is dropped; and it, moreover, may serve as a means to guide and -limit the movement ot' the adjusting-slide.

in one piece` 1 containing the phosphate therefore, must be y My invention further consists in combining, with the bottom and the adjusting and cnt-olf slides usually applied to the same, a series oi holding-frames,one of said holders being applied to each discharge-opening in the bottom, and constructed and arranged so that bot-h slides will play easily in the same holder, thus simplifying greatly the construction of this portion of the drill. I.

I prefer securing the seed-hopper or box to the frame of the machine, by a hinged connection, which will permit the box to be turned over, so as to expose the bottom whenever-an y portion ofthe mechanism there located, or any partei' the machine immediately under the box. requires to be adjusted orhandlcd ior any purpose.

In machines ot' this class it is usual, lor the purpose of conducting the sccd ii'om the box, to employ metal tubes attached to the box and i'ramc. In order, however, touse tubes of this kind, and yet to so arrange them as to permit thc iree movement oi' the hinged box, as provided for in the prtaieding paragraph, I use open metallic spouts or i'unncls, which are attached to the frame of the machine, and have no connection with'the box.

Wit-h the grain-drill I use a lertiliner-attachment, such, i'or instance, as described in Letters latent heretofore granted me; and the grain-box and box'for or other fertilizer are placed Side by side.

In order to allow the wheat and phosphate to Jail together to the ground,""I make the mouths of the open metallic spouts or tunnels large enough to come under the discharge-openings in both boxes, so that the grain and phosphate will run down together through the same spout; and I also place the spouts at such dist-ance below the bottoms ofthe boxes, that it can readily be seen whether the machine is feeding the wheat and phosphate as required.

'Io enable others skilled in the art to understand and use my invention, I will now proceed to describe more fully the manner in which the saine ils or may be carried into cticct, by reference to the accompanying drawings.

'.lhe thin iron bottom is cast wit-lfdischargempenings, as seen in iigs.-2, 3, and 4, the surface of the bottoni being i'orned so as to'slant on all sides toward the openings, thus forming, in eiicct, a series ot' shal low tunnels, in the lower part of which the openings are situated. When thus formed, there is no' ext-ended horizontal surface upon which the refuse matter can accumulate, but the. ,grain and dust, tte., are all carl ried forward gradually over the inclined surtaces to the openings through which they are discharged* 0n one ot` the sides of each opening is cast cut-oitl projection or lip7 (l. These cut-Otis project below the bottom, as shown plainly in tig. 2, and tit in slots or openings made in the adjusting-slide, thus serving to guide and determine the movement of the slide. lhe adjusting-slide fits closely against the openings, and the. size of the discharge-apertures is regulated by adjustine; the slide, so that the ends ot' the slots formed in it shall be at the proper distance from the front ends ofthe cut-off projections or lips,

The two slides C 3') are placed together, the former against the bottom of the box, and the. latter against the forme-r, and both are maintained in position by -means oi' the frames or holders F, one of which is applied and secured to the bottom, under each openin". The two slides lit in the saine holder, and are capable ot' being` moved ii'eely, endwise, in either direction, the one for the purpose ot' adjusting the size of the discharge-aperture, the other t'or closing the aperture. entirely whenever desired.

The mechanism for operating, and the mode ot` operation ot' these slides, are too well lgnown to require description.

lhc use of one holder to receive, support, and maintain the t-n'o slides, at the. same thne leaving them i'rec to play, is advantageous in many ways, as it not only simplifies theconst-ructiou ot' this portion ot' the machine, but admits oi' the parts being more easily adjusted or detached than has been practicable heretofore.

.lfhe front i'eetol' the box are hinged, a-t b, to the frame oft-he machine, as shown plainly in the drawings. The advantage ot' this hinged connection between the box and the ii'ame is apparent, for the box can be turned over so as to expose the bottom and all the. parts connected therewith, which can be then got at without any diliiculty; and italso admits of access being had to that portion ot the mechanism attached io the frame., which would otherwise be. covered and hid by the box. .ihe. box can also be detached with ;reat ease, and removed from the machine whenever uesired. .lt' thc hopper-box ot' the fertilizer-attachment, hereinbet'orc referred to, he it will, ofcourse, move with it.

attached to the box, l

'.lhe metallic spouts, when the bo\ is hinged, are secured only to the frame of the machine, as shown in the drawings, ami have' no connection with the box. 'lhey are arranged under the openings in the boxes, in the usual manner, and, as seen in figs. 3 and 4, are made large enough to receive also the phosphate from the fertilizer-box, wh'ich is placed in rear ofthe grainbox, so that the grain and phosphate run through the` same spout to the ground. rlhe spouts are placed a suitable distance below the box, so as to leave be.- tween them and the bottom ot' the box an opening, through which it can be readily ascertained whether' the machine is dropping, the rcouiredquantity of grain and phosphate.

Having now described my invention, and the manner in which the same is or may be carried into effect,

What I. claim, and desire to secure by Letters Patent, is-

1. A east-iron bottom, for Idie seed-boxesof graindrlls, formed substantially as shown and described.

2. The metallic bottom, when cast with a cut-ofiT projection or lip at each discharge-opening, substantially as shown and set forth.

3. The combination of the cut-ott projection or lip, cast on the bottom oi' the seed-box, and formed as specified, with the slotted adjusting-slide, substantially as herein described.

4. rlhe employment, in combination with the adjusting ami eut-ott slides, of the frames or holders, applied and secured to the bottom of the seed-box at the discharge-openings, under the arrangement described, so that the slides, while held in and mailitained b v said holders, shall be free lto slide back and forth upon each other, as and for forth. y

5. The combination of the hinged seed-box, with the large open spouts supported upon the frame of the machine, and arranged under and at suitable distance from the discharge-apertures in the feed-box, substantially as and for the purposes shown and set forth.

In testimony whereof, I have signed my name to this specification, before two subscribing witnesses.
